Abstract: The near-space wind measurement is important to atmospheric dynamics, numerical weather prediction and guarantee of aerospace system. A 60 km Rayleigh Doppler lidar was developed to measure the wind of near space. This lidar was based on theory of the double-edge molecular technique. The system included three independent subsystems:one points to the zenith; the two others were tilted at 30 from the zenith with eastward and northward pointing, respectively. It emited 355 nm laser and could measure the wind within 15 km to 60 km. To validate the performance of the lidar and achieve wind data, field experiment of three months was carried out in the second half year of 2014, comparison of the wind data which showed good agreement with radiosonde.
